DollaTek PWM DC motor speed controller 9-60V/12A/500W motor fan controller encoder dimming speed control

• Using two original high-voltage low-resistance MOS transistors and pre-driver, the performance is better and more stable, supporting high-voltage and high-power.
• You can set the duty cycle, the upper and lower limits of the duty cycle and the working frequency, so that customers can operate and use according to the working characteristics of their own motors.
• The digital encoder knob adjusts the speed of the motor, which is higher in accuracy and consistency than ordinary potentiometers, and will not cause drift.
• Motor soft start function, the current increases slowly when starting the motor, no impact current, effectively protects the motor, and prolongs the service life of the motor
• It comes with a start-stop button and can be controlled by an external switch to meet customers' various control needs.
